Association between a changeable lifestyle, sedentary behavior, and suicide risk: A systematic review and meta-analysis.

BACKGROUND: Suicide and self-injury have become increasingly serious public health crises. Yet current evidence about the association between sedentary behavior (SB) and suicide is inconclusive. We explore the relationship between SB and suicide behavior to provide intervention measures to change the risk factors of the latter. METHODS: We searched PubMed, Embase, Cochrane Library, and Web of Science from database inception to September 10, 2023. Adjusted odds ratios (ORs) with 95 % confidence intervals (CIs) were used as effect measures. Subgroup analysis was conducted based on gender, regions and countries, age, and study type. RESULTS: A total of 13 studies were included. According to the meta-analysis of suicide type, compared with individuals without sedentary behavior, individuals with sedentary behavior have a higher risk of suicide attempt (OR = 1.23, 95%CI: 1.15-1.37, p < 0.001), suicide ideation (OR = 1.47, 95%CI:1.28-1.68, p < 0.001) and suicide plan (OR = 1.30, 95%CI:1.16-1.44, p < 0.001). We conducted multiple subgroup analyses for different suicidal behaviors. The analysis found that SB can increase the risk of suicide attempt in different subgroups of different genders, different research centers, Africa, and adolescents; SB can increase the risk of suicide ideation in the subgroups of different genders and ages, different research centers, Asia and Africa; SB can increase the risk of suicide plan in the subgroups of different genders, multi-center study, Africa, and adolescents. LIMITATIONS: Future research should focus on objective SB measurement and explore its dose-response relation and time limit. CONCLUSION: A sedentary lifestyle is associated with suicide behavior risk, with varying effects across age groups and regions, as evidenced in both single-center and multi-center studies.

Abnormal expression of miR-3653-3p, caspase 1, IL-1ß in peripheral blood of schizophrenia.

Schizophrenia (SCZ) is a chronic, highly relapsing, severe mental disorder with an unclear etiology. Cytokine-mediated neuroimmune abnormalities have been repeatedly revealed. IL-1ß was reported to play a vital role in expanding the inflammatory response. However, the underlying molecular mechanism is poorly understood. In this study, we found that miR-3653-3p with the NLRP3 binding site in Targetscan was differentially expressed in miRNA high-throughput sequencing in schizophrenia (SCZ), and indeed, its downregulation in SCZ peripheral blood was also verified by RT-qPCR (P-value = 0.015). Furthermore, we found that the mRNAs of caspase 1 and IL-1ß are elevated in people who suffer from SCZ (P = 0.044 and P = 0.001, respectively). Moreover, the interaction of NLRP3, Caspase1, and IL-1ß was found in the peripheral blood of patients with SCZ. The expression level of miR-3653-3p was negatively correlated with NLRP3 and IL-1ß mRNA contents (r = 0.487, P = 0.04 and r = 0.508, P = 0.037, respectively). NLRP3 mRNA was positively correlated with caspase1 mRNA. Meanwhile, the expression of miR-3653-3p was also negatively correlated with negative symptom subscores of PANSS (r = 0.450, P = 0.046). IL-1ß mRNA is positively correlated with the total scores of PANSS (r = 0.690, P = 0.002) and the sub-scores of general psychopathology of PANSS (r = 0.583, P = 0.014). Additionally, a significant positive relationship exists between IL-1ß and the total duration (r = 0.638, P = 0.006). We found that the combination of miR-3653-3p, caspase 1, and IL-1ß have better diagnostic values. The results indicate that miR-3653-3p, caspase 1, and IL-1ß can potentially be biomarkers of SCZ, identifying negative symptoms or a chronic course. A further understanding of the involvement of IL-1ß in SCZ may be a crucial molecular effector for the chronic course to intervene.

Self-esteem and professional identity among male nurses and male nursing students: mediating roles of perceived prejudice and psychological distress.

Introduction: There are not enough nurses around the world, and there are even fewer male nurses. It has not been easy for men to become nurses because of stereotypes about the roles of men and women in the workplace, which lead to prejudice and discrimination. This study explored how the self-esteem of male nurses and male nursing students affects their professional identity in an environment where stereotypes and social prejudice exist. This study also examined the differences of relevant variables in different sociodemographic characteristics of the research subjects in a Chinese social context. Methods: By purposive and snowball sampling, 464 male nurses and male nursing students were surveyed through questionnaires from November 2021 to January 2022. Data analysis was performed using SPSS 25.0 and PROCESS Macro 3.3. Results: Self-esteem could indirectly affect professional identity through perceived prejudice and psychological distress. Nonetheless, self-esteem still had a significant direct effect on professional identity. The total mediating effect accounted for 32.816% of the total effect, and the direct effect accounted for 67.184% of the total effect. Also of note was that 81.7% of participants reported experiencing psychological distress. Discussion: To improve the professional identity of male nurses and male nursing students, nursing educators and administrators should do the following: protect and improve their self-esteem; take steps to reduce social prejudice against them; value their mental health and alleviate their psychological distress.

Whole transcriptome analysis reveals dysregulation of molecular networks in schizophrenia.

To characterize the regulatory relationships between different types of transcripts and the altered molecular networks in schizophrenia (SCZ), we performed a whole transcriptome study by quantifying mRNAs, long noncoding RNAs (lncRNAs), miRNAs, and circular RNAs (circRNAs) in the same individuals simultaneously. A total of 807 dysregulated genes showed differential expression in SCZ cases compared with controls. Network-based analysis revealed dysregulation of molecular networks in SCZ. Finally, integration of the transcriptome data with published data identified promising SCZ candidate genes. Our study reveals that dysregulated molecular networks and regulatory relationships between different types of transcript may have a role in SCZ.

Circular non-coding RNA circ_0072088 serves as a ceRNA, targeting the miR-1225-5p/WT1 axis to regulate non-small cell lung cancer cell malignant behavior.

BACKGROUND: Circular RNA (circRNA) circ_0072088 has been reported to be associated with NSCLC cell growth, migration, and invasion. However, the role and mechanism of circ_0072088 on NSCLC development have not yet been determined. METHODS: Circ_0072088, microRNA-1225 (miR-1225-5p), and Wilms' tumor (WT1) suppressor gene level was detected by reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Migration, invasion, and apoptosis were detected using transwell and flow cytometry assays. Matrix metallopeptidase 9 (MMP9), hexokinase 2 (HK2), and WT1 were examined using western blot assay. The biological role of circ_0072088 on NSCLC tumor growth was examined by the xenograft tumor model in vivo. Circular RNA Interactome and TargetScan were used to predict the binding between miR-1225-5p and circ_0072088 or WT1, followed by confirmation using a dual-luciferase reporter. RESULTS: Circ_0072088 and WT1 were highly expressed in NSCLC tissues and cells, and miR-1225-5p was decreased. Knockdown of circ_0072088 might repress migration, invasion, and glycolysis, and facilitate apoptosis of NSCLC cells in vitro. Circ_0072088 silencing also blocked NSCLC tumor growth in vivo. Mechanistically, circ_0072088 acted as a sponge of miR-1225-5p to regulate WT1 expression. CONCLUSION: Circ_0072088 knockdown could inhibit cell growth, migration, invasion, and glycolysis partially by regulating the miR-1225-5p/WT1 axis, thus providing a promising therapeutic target for NSCLC treatment.

Exploring the association of addiction-related genetic factors with non-suicidal self-injury in adolescents.

Background: Non-suicidal self-injury (NSSI) is self-injurious behavior without suicidal intent commonly seen in the adolescent population and poses a serious threat to the life safety of adolescents. Related researches suggest a possible correlation between addiction and the occurrence of NSSI. This study aimed to explore the correlation between addiction and NSSI from a molecular biological perspective by analyzing the differential expression of addiction-related genes in NSSI patients. Methods: (1) The association between addiction and non-suicidal self-injury in a Chinese adolescent population was verified with the help of questionnaires on substance and non-substance addictions and non-suicidal self-injury among 1,329 adolescents in China, (2) Screening for key genes associated with addiction by bioinformatics analysis, and (3) RT-qPCR experiment was performed to validate key genes and Receiver Operating Characteristic curves were plotted for target genes. Results: (1) Substance and non-substance addictions were all significantly correlated with non-suicidal self-injury, (2) Four target genes: SERPINA3, SLC14A1, RPS6 and RPS3A were screened by bioinformatics technique, and (3) Relative quantitative analysis by RT-qPCR revealed that the expression levels of SLC14A1 (p < 0.01), RPS6 (p < 0.05) and RPS3A (p < 0.01) were significantly higher in NSSI patients than in healthy controls. Conclusion: (1) The significant association between addiction and NSSI exists in the Chinese adolescent population and (2) Addiction-related genes SLC14A1, RPS6, and RPS3A are differentially expressed in adolescents with NSSI. The genes have the potential to become biological markers for the diagnosis of NSSI.

Long-term trend analysis of liver cancer survival rate in Qidong region, Jiangsu Province, 1972-2019 / 中华肝脏病杂志

Objective: To analyze the incidence and survival rate of liver cancer cases in the entire population in the Qidong region from 1972 to 2019, so as to provide a basis for prognosis evaluation, prevention, and treatment. Methods: The observed survival rate (OSR) and relative survival rate (RSR) of 34 805 cases of liver cancer in the entire Qidong region population from 1972 to 2019 were calculated using Hakulinen's method with SURV3.01 software. Hakulinen's likelihood ratio test was used for statistical analysis. Age-standardized relative survival (ARS) was calculated using the International Cancer Survival Standard. The Joinpoint regression analysis was performed with Joinpoint 4.7.0.0 software to calculate the average annual percentage change (AAPC) of the liver cancer survival rate. Results: 1-ASR increased from 13.80% in 1972-1977 to 50.20% in 2014-2019, while 5-ASR increased from 1.27% in 1972-1977 to 27.64% in 2014-2019. The upward trend of RSR over eight periods was statistically significant (χ (2) = 3045.29, P < 0.001). Among them, male 5-ASR was 0.90%, 1.80%, 2.33%, 4.92%, 5.43%, 7.05%, 10.78%, and 27.78%, and female 5-ASR was 2.33%, 1.51%, 3.35%, 3.92%, 3.84%, 7.18%, 11.45%, and 29.84%, respectively. There was a statistically significant difference in RSR between males and females (χ (2) = 45.68, P < 0.001). The 5-RSR for each age group of 25-34 years old, 35-44 years old, 45-54 years old, 55-64 years old, 65-74 years old, and 75 years old were 4.92%, 5.29%, 8.17%, 11.70%, 11.63%, and 9.60%, respectively. There were statistically significant differences in RSR among different age groups (χ (2) = 501.29, P < 0.001). The AAPC in Qidong region from 1972 to 2019 for 1-ARS, 3-ASR, and 5-ARS were 5.26% (t = 12.35, P < 0.001), 8.10% (t = 15.99, P < 0.001), and 8.96 % (t = 16.06, P < 0.001), respectively. The upward trend was statistically significant in all cases. The AAPC of 5-ARS was 9.82% in males (t = 14.14, P < 0.001), and 8.79% in females (t = 11.48, P < 0.001), and the upward trend was statistically significant in both. The AAPC of 25-34 years old, 35-44 years old, 45-54 years old, 55-64 years old, 65-74 years old, and 75 years old were 5.37% (t = 5.26, P = 0.002), 5.22% (t = 5.66, P = 0.001), 7.20% (t = 6.88, P < 0.001), 10.00% (t = 12.58, P < 0.001), 9.96% (t = 7.34, P < 0.001) and 8.83% (t = 3.51, P = 0.013), and the upward trend was statistically significant. Conclusion: The overall survival rate of registered cases of liver cancer in the Qidong region's entire population has greatly improved, but there is still much room for improvement. Hence, constant attention should be paid to the study on preventing and treating liver cancer.

[Explore the mechanism of astragaloside IV-PESV on proliferation, migration, and autophagy of prostate cancer cells based on the PI3K/AKT signaling pathway].

OBJECTIVE: Explore the effects of Astragaloside IV and Scorpion Venom Peptide on the activity, migration, apoptosis, cell cycle, autophagy, and the expression of proteins related to the PI3K/AKT signaling pathway in prostate cancer cells. METHODS: The human prostate cancer cell lines LNCaP and PC-3 were randomly divided into blank control group, Astragaloside IV group, Scorpion Venom Peptide group, Astragaloside IV-Scorpion Venom Peptide group, and rapamycin (positive drug group). After corresponding drug treatments for 24 hours, logarithmic growth phase tumor cells were collected for testing. Cell proliferation was assessed using a Cell Counting Kit-8 (CCK-8) assay, Transwell assay, apoptosis assay, cell cycle assay, and immunofluorescence analysis were performed to detect the activity and migration capacity of prostate cancer cells in each group, as well as their effects on apoptosis, cell cycle, and the autophagy target LC3. Western blot analysis was employed to measure the protein expression levels of p-PI3K, p-Akt, p-mTOR, Beclin1, LC3, and P62. RESULTS: Compared to the blank control group, the Astragaloside IV-Scorpion Venom Peptide group exhibited a significant decrease in the activity of prostate cancer cells (P<0.05) and a reduction in the cell invasion ability (migration capacity) (P<0.05). The early apoptosis rate (LR), late apoptosis rate (UR), and total apoptosis rate all increased (P<0.05). The proportion of cells in the G1 phase increased (P<0.05), while the proportion in the G2+S phase decreased (P<0.05). The immunofluorescence expression of LC3 significantly increased (P<0.05). The expression of LC3Ⅱ and Beclin1 proteins in prostate cancer cells LNCaP and PC-3 was upregulated (P<0.05), while the expression of P62, p-PI3K, p-AKT, and p-mTOR proteins was downregulated (P<0.05).Astragaloside IV-Scorpion Venom Peptide is superior to the Astragaloside IV group or Scorpion Venom Peptide group alone in inhibiting the activity and migration capacity of prostate cancer cells, suppressing cell mitosis, promoting early apoptosis, upregulating the expression level of LC3, and inhibiting the PI3K/AKT pathway while promoting autophagy (P<0.05). CONCLUSION: The mechanism by which Astragaloside IV-Scorpion Venom Peptide inhibits the proliferation and migration of prostate cancer cells, suppresses cell mitosis, promotes early apoptosis, and enhances autophagy may be related to the inhibition of the PI3K/AKT pathway.

In-depth investigations of the molecular basis underlying sex differences among middle-aged and elderly schizophrenia populations.

Sex can influence almost all aspects of schizophrenia. However, the molecular mechanisms underlying sex differences in schizophrenia remain poorly understood. In this project, the dataset GSE107638 containing neuronal RNA-seq data and age/sex information of individuals with or without schizophrenia were retrieved. Schizophrenia samples were divided into young male (M-1), young female (F-1), middle-aged and elderly male (M-2) and middle-aged and elderly female (F-2) groups. Next, green/yellow/turquoise modules related to the M-2 trait and turquoise module correlated with the F-2 trait were identified by weighted correlation network analysis (WGCNA) analysis (soft thresholding power: 13; min module size: 200). Crucial genes in the M-2 green, M-2 turquoise and F-2 turquoise modules were identified by WGCNA, gene significance/module membership, and protein-protein interaction (PPI) analysis. Moreover, 2067 and 934 differentially expressed genes (|log2 fold-change| ≥0.58 and P-value < 0.05) in M-2 and F-2 schizophrenia subgroups versus same-age and same-sex counterparts were identified, respectively. Additionally, 82 core genes in the M-2 turquoise module and 4 hub genes in the F-2 turquoise module were differentially expressed in M-2 and F-2 schizophrenia subgroups versus their counterparts, respectively. Among the 82 hub genes, 15 genes were found to be correlated with neuronal development by the Kyoto Encyclopedia of Genes and Genomes enrichment analysis. Also, 2 potential PPI networks related to neuronal development were identified. Taken together, multiple potential hub genes and 2 potential neurobiological networks related to schizophrenia sex differences and disease progression were identified among middle-aged and elderly schizophrenia populations.

Development of highly potent non-covalent inhibitors of SARS-CoV-2 3CLpro

The SARS-CoV-2 virus is the causal agent of the ongoing pandemic of coronavirus disease 2019 (COVID-19). There is an urgent need for potent, specific antiviral compounds against SARS-CoV-2. The 3C-like protease (3CLpro) is an essential enzyme for the replication of SARS-CoV-2 and other coronaviruses, and thus is a target for coronavirus drug discovery. Nearly all inhibitors of coronavirus 3CLpro reported so far are covalent inhibitors. Here, we report the development of specific, non-covalent inhibitors of 3CLpro. The most potent one, WU-04, effectively blocks SARS-CoV-2 replications in human cells with EC50 values in the 10-nM range. WU-04 also inhibits the 3CLpro of SARS-CoV and MERS-CoV with high potency, indicating that it is a pan-inhibitor of coronavirus 3CLpro. WU-04 showed anti-SARS-CoV-2 activity similar to that of PF-07321332 (Nirmatrelvir) in K18-hACE2 mice when the same dose was administered orally. Thus, WU-04 is a promising drug candidate for coronavirus treatment. One-Sentence SummaryA oral non-covalent inhibitor of 3C-like protease effectively inhibits SARS-CoV-2 replication.

Clinical Prediction of Heart Failure in Hemodialysis Patients: Based on the Extreme Gradient Boosting Method.

Background: Heart failure (HF) is the main cause of mortality in hemodialysis (HD) patients. However, it is still a challenge for the prediction of HF in HD patients. Therefore, we aimed to establish and validate a prediction model to predict HF events in HD patients. Methods: A total of 355 maintenance HD patients from two hospitals were included in this retrospective study. A total of 21 variables, including traditional demographic characteristics, medical history, and blood biochemical indicators, were used. Two classification models were established based on the extreme gradient boosting (XGBoost) algorithm and traditional linear logistic regression. The performance of the two models was evaluated based on calibration curves and area under the receiver operating characteristic curves (AUCs). Feature importance and SHapley Additive exPlanation (SHAP) were used to recognize risk factors from the variables. The Kaplan-Meier curve of each risk factor was constructed and compared with the log-rank test. Results: Compared with the traditional linear logistic regression, the XGBoost model had better performance in accuracy (78.5 vs. 74.8%), sensitivity (79.6 vs. 75.6%), specificity (78.1 vs. 74.4%), and AUC (0.814 vs. 0.722). The feature importance and SHAP value of XGBoost indicated that age, hypertension, platelet count (PLT), C-reactive protein (CRP), and white blood cell count (WBC) were risk factors of HF. These results were further confirmed by Kaplan-Meier curves. Conclusions: The HF prediction model based on XGBoost had a satisfactory performance in predicting HF events, which could prove to be a useful tool for the early prediction of HF in HD.

Heme peroxidases are responsible for the dehydrogenation and oxidation metabolism of harmaline into harmine.

Harmaline and harmine are ß-carboline alkaloids with effective pharmacological effects. Harmaline can be transformed into harmine after oral administration. However, enzymes involved in the metabolic pathway remain unclear. In this study, harmaline was incubated with rat liver microsomes (RLM), rat brain microsomes (RBM), blood, plasma, broken blood cells, and heme peroxidases including horseradish peroxidase (HRP), lactoperoxidase (LPO), and myeloperoxidase (MPO). The production of harmine was determined by a validated UPLC-ESI-MS/MS method. Results showed that heme peroxidases catalyzed the oxidative dehydrogenation of harmaline. All the reactions were in accordance with the Hill equation. The reaction was inhibited by ascorbic acid and excess H2O2. The transformation of harmaline to harmine was confirmed after incubation with blood, plasma, and broken blood cells, rather than RLM and RBM. Harmaline was incubated with blood, plasma, and broken cells liquid for 3 h, and the formation of harmine became stable. Results indicated an integrated metabolic pathway of harmaline, which will lay foundation for the oxidation reaction of dihydro-ß-carboline. Moreover, the metabolic stability of harmaline in blood should not be ignored when the pharmacokinetics study of harmaline is carried out.

Changes in the tight junctions of the testis during aging: Role of the p38 MAPK/MMP9 pathway and autophagy in Sertoli cells.

Impaired tight junction (TJ) function and autophagy and the activated p38 mitogen-activated protein kinase (MAPK)/matrix metalloproteinase 9 (MMP9) pathway in Sertoli cells cause spermatogenic disorders. However, it is unclear whether reduced TJ barrier function and autophagy and the activated p38 MAPK/MMP9 pathway in Sertoli cells are closely associated with age-related testicular dysfunction. Thus, we evaluated these changes in Sertoli cells using 6-, 12-, 18-, and 24-month-old Sprague-Dawley rats. The results showed that testicular morphology gradually degenerated, as evidenced by increased exfoliated germ cells, decreased seminiferous tubule diameter and seminiferous epithelium height, and reduced the numbers of spermatogonia, primary spermatocytes and spermatids during the process of aging. In addition, the TJs formed by adjacent Sertoli cells were progressively destroyed accompanied by an abnormal ultrastructure and decreased expression of the TJ proteins zonula occludens-1 (ZO-1), occludin, and claudin-11 with aging. Furthermore, the expression of phosphorylated p38MAPK and MMP-9 in Sertoli cells and testis gradually increased, and the expression of occludin co-localizated with MMP-9 progressively decreased. Meanwhile, autophagy levels also gradually decreased, including decreased autophagic vacuole formation and weak expression of light chain 3 (LC3) and autophagy-related 5 (Atg5) in Sertoli cells. Taken together, our results indicate that aging causes impaired TJ barrier function and degeneration of seminiferous tubules. The mechanism might be related to the activated p38MAPK/MMP9 pathway and inactivated autophagy in Sertoli cells.

Eczema is a shared risk factor for anxiety and depression: A meta-analysis and systematic review.

Globally, anxiety and depression are the most common psychiatric disorders that add large burdens to individuals and society; however, the mechanisms underlying these disorders are unclear. Several studies have found that eczema is a shared risk factor for both these conditions. We identified and evaluated eligible observational studies from EMBASE and PubMed. In total, 20 relevant cohort and case-control studies comprising 141,910 patients with eczema and 4,736,222 control participants fulfilled our established criteria. Information extracted included study design, location, sample size, sex distribution of cases and controls or reference cohorts, measurements of outcomes, odds ratio (OR) with 95% confidence interval (CI), and adjusted factors for exposure associated with outcome risk. The meta-analysis was performed by calculating the pooled OR with 95% CI, and heterogeneity was assessed using Cochrane Q and I2 statistics. The pooled effect showed a positive association (n = 4,896,099, OR = 1.63, 95% CI [1.42-1.88], p<0.001) between eczema and depression or anxiety, with positive associations also observed in the depression (n = 4,878,746, OR = 1.64, 95% CI [1.39-1.94], p<0.001) and anxiety (n = 4,607,597, OR = 1.68, 95% CI [1.27-2.21], p<0.001) groups. Subgroup and sensitivity analyses confirmed that these findings were stable and reliable. This study suggests that eczema is associated with an increased risk of developing depression and anxiety, which may assist clinicians in the prevention or treatment of these disorders.

[Magnetic resonance and magnetoelectric therapy combined with Danhong Tongjing Prescription for the treatment of CP/CPPS and its effects on secretory IgA, vascular cell adhesion molecule-1 and interleukin-8].

OBJECTIVE: To investigate the therapeutic effect of magnetic resonance and magnetoelectric therapy (MRMT) combined with oral Danhong Tongjing Prescription (DTP) on chronic prostatitis / chronic pelvic pain syndrome (CP/CPPS) and the changes in the levels of cytokine-secretory IgA (sIgA), vascular cell adhesion molecule-1 (VCAM-1) and interleukin-8 (IL-8) after treatment. METHODS: Totally 200 patients with CP/CPPS of the qi stagnation and blood stasis type were randomly divided into three groups to receive MRMT + DTP (n = 68), MRMT (n = 67) and DTP (n = 65), respectively, all for 12 weeks. After treatment, we compared the total effectiveness rate, patients' scores on NIH-CPSI and traditional Chinese medicine (TCM) syndrome, and the expressions of sIgA, VCAM-1 and IL-8 in the EPS among the three groups of the patients. RESULTS: After treatment, the patients in the MRMT + DTP group, compared with those in the MRMT and DTP groups, showed a significantly higher total effectiveness rate (86.76% vs 79.10% and 78.46%, P < 0.05 and P < 0.01) and lower scores on pain or discomfort (4.61 ± 2.37 vs 5.86 ± 3.26 and 6.94 ± 2.25 P < 0.01), abnormal urination symptoms (2.98 ± 1.75 vs 3.85 ± 2.01 and 3.94 ± 1.95) and quality of life (3.26 ± 1.87 vs 4.54 ± 2.13 and 4.69 ± 1.72). There were statistically significant differences in the total NIH-CPSI scores among the three groups (10.64 ± 5.91 vs 4.59 ± 6.87 vs 15.54 ± 5.76, P < 0.05). The MRMT + DTP group also exhibited a remarkably lower TCM syndrome score than the MRMT and DTP groups (5.56 ± 3.42 vs 7.37 ± 4.57 and 8.16 ± 3.65, P < 0.05). Compared with the baseline, the expressions sIgA, VCAM-1 and IL8 were all markedly decreased after treatment in the MRMT + DTP (Z = －7.170, Z = －7.182, Z = －7.18), MRMT (Z = －6.802, Z = －6.973, Z = －6.768) and DTP groups (Z = －5.963, Z = －6.990 Z = －5.618) (P < 0.05), even more significantly in the former than in the latter two groups (P < 0.05). CONCLUSION: Magnetic resonance and magnetoelectric therapy combined with Danhong Tongjing Prescription has a good therapeutic effect on CP/CPPS of the qi stagnation and blood stasis type, probably by regulating sIgA, VCAM-1, IL-8 and other cytokines, activating the function of the immune system, inhibiting inflammation, and promoting the absorption of local inflammatory substances.

Prediction model for cardiovascular disease risk in hemodialysis patients.

PURPOSE: To derive and validate a prediction score for cardiovascular disease (CVD) risk in hemodialysis patients in China. METHODS: Three hundred and eighty-eight patients with regular hemodialysis for more than 3 months were recruited from January 1, 2015 to September 30, 2019 and followed up till May 31, 2020. We derived a prediction score using all participants as a training data set and validated using a bootstrap validation data set. Discriminatory ability of the prediction score was assessed by the area under the receiver operating characteristic curve (AUC). RESULTS: Of 388 patients without CVD at baseline, 132 developed first CVD events during an average follow-up of 3.27 (inter-quartile range = 3.08) years. Of 26 clinical parameters, age, hypertension, diabetes and abnormal white blood cell (WBC) count were identified as significant predictors and included in the prediction model. Compared to those without any of these risk factors, those with one, two, and three to four points showed increased risks of CVD, with the adjusted hazards ratio and 95% confidence interval (CI) being 3.29 (1.17-9.26), 7.42 (2.68-20.51) and 15.43 (5.44-43.75), respectively. The score showed satisfactory discriminatory ability in both training and validation data set (AUC = 0.7025, 95% CI 0.6520-0.7530, and 0.6876, 95% CI 0.6553-0.7200, respectively). CONCLUSION: We derived and validated a prediction score for CVD risk in hemodialysis patients in China. Given there is a rapid increase in the number of hemodialysis patients, this simple point score can be used to identify high-risk individuals in clinical practice for more precise and efficient personalized treatment.

Objective: The survival of colorectal cancer in Qidong City, Jiangsu Province from 1972 to 2016 was analyzed to provide a basis for the evaluation of prognosis and the formulation of prevention and control measures. Methods: Colorectal cancer data were obtained from the Qidong Cancer Registration and Reporting System, and the follow-up was up to December 31, 2021. The observed survival rate (OSR) and relative survival rate (RSR) were calculated by SURV 3.01 software, and the trend test was performed by Hakulinen's likelihood ratio test. The Joinpoint regression model was used to calculate the average annual percentage change (AAPC) of survival, and the ARIMA model was used to predict the trend of colorectal cancer survival. Results: There were 8 637 new cases of colorectal cancer in Qidong from 1972 to 2016. Dividing 1972-2016 into 9 periods at 5-year intervals, the 5-year OSR from 1972-1976 to 2012-2016 increased from 21.86% to 48.86%, and the 5-year RSR increased from 26.45% to 59.91%. The increasing trend of RSR was statistically significant (χ(2)=587.47, P<0.001). From 1972 to 2016, the survival rates of colorectal cancer in different sexes in Qidong were similar, and the 5-year RSR was 44.63% for men and 44.07% for women. Since the 1990s, the 5-year OSR and RSR for men have been lower than those for women. From 1972 to 2016, the 5-year RSR of colorectal cancer in Qidong was significantly improved in the 65-74 and ≥75-year-old groups, but the survival rate of the ≥75-year-old group was still the lowest (36.78%), followed by the 35-44-year-old group ( 43.04%). The time trend showed that the overall AAPC of colorectal cancer 5-year RSR in Qidong from 1972 to 2016 was 2.50% (t=16.45, P<0.001). The upward trend of different sexes was consistent, and the increase was greater in women (AAPC for males=2.18%, AAPC for females=2.54%, both P<0.05). The 5-year RSR of colorectal cancer in each age group showed an upward trend, and the AAPCs of the 35-44, 45-54, 55-64, 65-74, and ≥75-year-old groups were 1.54%, 1.83%, 2.00%, 3.51% and 4.35%, respectively (all P<0.05). The prediction results of colorectal cancer survival rate showed that the 5-year RSR of colorectal cancer in Qidong will increase to 71.62% by 2026. Conclusions: The overall survival rate of colorectal cancer patients in Qidong has been greatly improved, but there is still room for improvement. We should continue to pay attention to the early diagnosis and early treatment of colorectal cancer.

A Case Series of Olfactory Dysfunction in Imported COVID-19 Patients: A 12-Month Follow-Up Study / 生物医学与环境科学（英文）

Objective@#The scientific community knows little about the long-term influence of coronavirus disease 2019 (COVID-19) on olfactory dysfunction (OD). With the COVID-19 pandemic ongoing worldwide, the risk of imported cases remains high. In China, it is necessary to understand OD in imported cases.@*Methods@#A prospective follow-up design was adopted. A total of 11 self-reported patients with COVID-19 and OD from Xi'an No. 8 Hospital were followed between August 19, 2021, and December 12, 2021. Demographics, clinical characteristics, laboratory and radiological findings, and treatment outcomes were analyzed at admission. We surveyed the patients via telephone for recurrence and sequelae at the 1-, 6-, and 12-month follow-up.@*Results@#Eleven patients with OD were enrolled; of these, 54.5% (6/11) had hyposmia and 45.5% (5/11) had anosmia. 63.6% (7/11) reported OD before or on the day of admission as their initial symptom; of these, 42.9% (3/7) described OD as the only symptom. All patients in the study received combined treatment with traditional Chinese medicine and Western medicine, and 72.7% (8/11) had partially or fully recovered at discharge. In terms of OD recovery at the 12-month follow-up, 45.5% (5/11) reported at least one sequela, 81.8% (9/11) had recovered completely, 18.2% (2/11) had recovered partially, and there were no recurrent cases.@*Conclusions@#Our data revealed that OD frequently presented as the initial or even the only symptom among imported cases. Most OD improvements occurred in the first 2 weeks after onset, and patients with COVID-19 and OD had favorable treatment outcomes during long-term follow-up. A better understanding of the pathogenesis and appropriate treatment of OD is needed to guide clinicians in the care of these patients.

Epidemic characteristics of stomach cancer mortality in Qidong during 1972-2016 / 中华肿瘤杂志

Objective: To describe the epidemic characteristics of stomach cancer mortality in Qidong between 1972 and 2016. Methods: The cancer registry data of stomach cancer death and population during 1972-2016 in Qidong was collected. The mortality of crude rate (CR), China age-standardized rate (CASR), world age-standardized rate (WASR), 35-64 years truncated rate, 0-74 years cumulative rate, cumulative risk, percentage change (PC), annual percent change (APC) were calculated. Results: During 1972-2016, a total of 15 863 (male: 10 114, female: 5 749) deaths occurred attributed to stomach cancer, accounting for 16.04% of all cancers, with CR of 31.37/100 000 (CASR: 12.97/100 000, WASR: 21.39/100 000). The truncated rate of 35-64, cumulative rate of 0-74, and cumulative risk were 28.86/100 000, 2.54%, and 2.51%, respectively. For male, the CR, CASR, WASR were 40.53/100 000, 17.98/100 000, 30.13/100 000, respectively, and for female, the CR, CASR, WASR were 22.45/100 000, 8.52/100 000, 13.92/100 000, respectively. Age-specific mortality analysis showed that the mortality of each age group under 25-year-old group was less than 1/100 000. The CR increased with age. The 50-year-old group reached and exceeded the average mortality of the population, and more than 80-year-old group reached the peak of death. During 1972-2016 in Qidong, The PCs in CR, CASR, and WASR of stomach cancer were 55.43%, -52.02%, -43.60%. The APC were 0.54%, -2.30%, -2.08%, respectively. Period mortality analysis showed that except for the 75-year-old group, the mortality of stomach cancer decreased significantly. Conclusions: The crude mortality of stomach cancer increases slightly in Qidong, while the CASR and WASR decrease significantly. However, stomach cancer is still one of the malignant tumors that most affect health and seriously threat lives.
